SYSTEM AND METHOD FOR NEGOTIATION OF MULTI-MEDIA CAPABILITIES ACROSS NETWORKS

摘要

A telecommunications system and method is disclosed for converting between networks for multi-media purposes by adding an attribute to the call control protocol to indicate the multi-media coding of the calling subscriber. This attribute is used to negotiate the multi-media coding between the different nodes involved in a call. Based on the negotiation, various Media Gateways (MG) can be selected to perform the necessary interworking.
